The Discovery of the Katipunan
On July 5, 1896, Manuél Sityar, a Spanish lieutenant of the guardia civíl stationed at Pasig, reported to Governor-General Ramón Blanco y Erenas the mysterious activities of certain Filipinos who had been gathering arms and recruiting men for some unknown purposes. On August 13, 1896, Fr. Agustín Fernández, an Augustinian curate of San Pedro, Makati, wrote to Don Manuél Luengo, Civil Governor of Manila, denouncing anti-Spanish meetings in his parish.
The Katipunan was finally discovered by the Spanish authorities six days after Fernández's letter to Luengo. On early August 19 1896, two Katipuneros, namely Teodoro Patiño and Apolonio de la Cruz, who were working for the Diario de Manila printing press had undergone misunderstanding regarding wages. Press foreman de la Cruz and typesetter Patiño fought over salary increase of two pesos, and de la Cruz tried to blame Patiño for the loss of the printing supplies that were used for the Kalayaan. As an action against de la Cruz, Patiño revealed the secrets of the society to his sister, Honoria Patiño, an inmate nun at the Mandaluyong Orphanage. That afternoon, on August 19, 1896, Honoria grew shocked and very upset to the revelation. The mother portress of the Orphanage, Sor Teresa de Jesus saw Honoria crying so she approached her. Honoria told everything she heard from her brother. At around 6:15 pm that day, Sor Teresa called Teodoro Patiño and advised him to tell everything he knew about the Katipunan through confession to Father Mariano Gíl.
Controlled by his fear of Hell, Teodoro went to Father Mariano Gíl, an Augustinian parish curate of the Tondo convent. Though he is willed to tell anything about the Katipunan, Teodoro confessed to Father Gíl that a lithographic stone was hidden in the press-room of Diario de Manila, which was used by the society for printing receipts. He also said that aside from the stone, there were also documents of membership
